Bill,
I'd be interested in your opinions on Micromelo - again I attach a jpeg - Debelius seems to use the name Micromelo undata for this animal, but I'd agree with you that it's unlikely that the same species is in the Atlantic - I'm not even certain that all the Indo-Pacific ones are a single species? Does anyone have a growth series - this individual seems to have no waves in it's brown longitudinal lines - but it was only about 7mm long.

I don't know of any growth series but if we keep on adding photos here we will end up with one ourselves! Marcus & Marcus (1967 - in American Opisthobranch Molluscs, Studies in Tropical Oceanography No 6) describe the anatomy of Caribbean specimens of Micromelo undata. By chance they describe and draw the larval shell (protoconch) and it does seem to have broad colour bands as in Clay's photo, but I am not sure from Marcus & Marcus, whether the colour is black or red in their material. .
